SADDLE FOR ATTACHING PIPES TO FEE-LINES.

Specification of Letters Patent.

Patented Dec. 24, 1912.

To all whom it may concern:

Be it known that I, FRANK N. SMITH, a citizen of the United States,residing at Bradford, in the county of McKean and State of Pennsylvania,have invented certain new and useful'Improvements in Saddles forAttaching Pipes to Pipe-Lines; and I do hereby declare the following tobe a full, clear, and exact'description of the in vention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention consists in the novel features hereinafter describedreference being had to the accompanying drawing which illustrates oneformin which I have contemplated embodying the invention and saidinvention is fully disclosed in the following description and claims.

Referring to the said drawing, Figure 1 represents a'perspective view ofa saddle embodying my invention with the gasket therefor removed fromits seat. Fig. 2 is a detail perspective view of the gasket for thesaddle shown in Fig. 1 before it is applied thereto. Fig. 3 1s a sectionof t e saddle block online 33 of Fig. 1 with the gasket in place. Fig. 4is a similar secv tion on line 44, Fig. 1.-

My invention relates to saddles for facilitating the attachment of abranch pipe to a pipe line without distur bing the inc and theembodiment of my invention which I have selected for purposes ofillustration herein, is a saddle adapted to be applied to a four inchpipe line for the purpose of connecting a one inch pipe thereto.

Referrin to the drawing, 1 re resents the saddle bloc which is usually 0cast metal and is provided with a. curved central recess 2, concentricwith the pipe upon which it is to be placed, in this instance a fourinch pipe. The block is also provided preferably with two pairs of boltholes, to receive the U-sha ed yokes or bails 3, 3, the end ortions 0which are passed through said olt holes and threaded to receive nuts 4,by means of which the saddle block is securely clamped to the pipe, theyokes or bails passin around the pipe. tion 0 the block 1 is providedwith an aperture 5, communicating with the curved recess 2, and threadedto receive the smaller pipe, in this case a one mch pipe. In order Thecentral porto make a tight joint between the saddle block and theexterior of the pi e I employ a gasket 6 which is forme of soft metalsuch as lead, of circular form and which engages an annular gasketreceiving portion of the recess 2 of the saddle block surrounding theaperture 5. As these saddles are fre uently attached to pipe lines intrenches an other places where access is difiicult for a workman, it isdesirable to secure the gasket in place so that the saddle may beapplied in a position most advantageous to the workman in turning thenuts and so that the entire saddle may be turned on the pipe or moved on.the same before the nuts are completely screwed up, to bring the saddleinto the required osition, without disturbing the gasket. 0 this end Ipreferably provide the saddle block with an annular gasket receivingrecess 7 in the curved face 2, surroundin the aperture 5, to receive thegasket 6 an in said recess I provide one or more interlocking sockets oroles 8, 8 to receive teats or projections 9, 9 on the gasket 6, as shown1n Figs. 2, 3 and 4. The teats or projections 9, 9 are made of such sizeand she e with respect to the holes 8, 8 as to fit t erein tightly, thatis to say with considerable frict1on,'so as to hold the gasket firmly inposition.

' The gasket 6 may be shaped to conform to the curved face 2, andannular packing recess 7 when made, if desired, but I prefer to form thegasket as a plain ring of lead, preferably circular in cross sectionwith the frictional interlocking projections 9 extending on one side ofthe same, as shown in Fig. 2, and the gasket being composed of softmetal, it can be readily pressed into the gasket receiving recess 7,theteats or projections being firmly pressed into the interlockinsockets 8, 8 of the saddle block by hand. is may be done by the operatorjust previous to applying the saddle to the pipe, or it may be done atthe place of manufacture, if desired, and the saddles sent out ready forattachment.

I prefer, however,

to huvethe gasket inserted at the time of ap lying, the, saddle.

- e frictional and interlocking engagement of the teats or projections 9of the gasket and the sockets :8 of the saddle block inoperativeposition while the saddle is bewill cause the gasket to be held andretained ing applied, and will permit the saddle to be moved around oralong the pipe without detaching or disturbing the position of thegasket.

It will be understood that after the nuts are screwed up tightly and thegasket is firmly compressed between the saddle block and the exterior ofthe pipe to which it is applied, a hole of slightly smaller diameterthan the aperture 5 is drilled in the pipe Wall, the drill beinginserted through aperture 5, and a pipe is then screwed into theaperture 5 to complete the connection.

What I claim and desire to secure by Lettors Patent is 1. In a saddlefor connecting pipes to pipe lines, the combination with a saddle blockprovided with a curved pipe engaging face, having an aperture thereinand an annular gasket receiving portion surrounding said aperture andmeans for clamping the saddle to a pipe, of a gasket of soft metaladapted to fit said annular gasket receiving portion, said portion andsaid gasket being provided with interlocking devices for holding thegasket in position with respect to said aperture in said block. 7,

2. In a saddle for connecting pipes to pipe lines, the combination witha saddle block provided with a curved pipe engaging face, having anaperture therein and an annular gasket receiving portion surroundingsaid aperture and means for clamping the saddle to a pipe, of a gasketof soft metal adapted to fit said annular gasket receiving portion, saidportion and said gasket being provided with frictionally engaginginterlocking devices for holding the gasket in position with respect tosaid block.

3; In a saddle for connecting pipes to pipe lines, the combination witha saddle block provided with a curved pipe engaging face, having anaperture therein, an annular gasket receiving portion surrounding saidpipe aperture, said annular gasket receiving portion being provided atseparated points with sockets extending into the saddle block, and meansfor clamping said block upon a pipe, of a gasket of soft metal providedat points registering with said sockets, with projections to enter saidsockets for holding the gusklst in position withjrespectto the said b 00l 4. In a saddle for connecting pipes to pipe lines, the combinationwith a saddle block provided with a curved pipe engaging face, having anaperture therein, an annular gasket receiving portion surrounding saidpipe aperture, said annular gasket receiving portion being provided atseparated points with sockets extending into the saddle block, and meansfor clamping, said block upon a pipe, of a gasket of soft metal providedat points registering with said sockets, with projections formedintegrally therewith, and of such size and shape as to frictionally fitsaid sockets and hold the gasket in position with respect to said block.

In testimony whereof I afiix my signature in the presence of twowitnesses.
